Abstract

A drain hole of a conventional rain water cover in cities is a rectangle with a width of 2-3cm so that leaves, silt, branches, paper scrapes, small rocks and the like can all enter into a drain pipe, part of or the whole drain pipe is blocked, water accumulation of the cities is caused due to the fact that water cannot flow smoothly, and water logging is caused. An anti-blocking rain water cover is composed of a desilting nest (1) and a draining nest (2), the width of the desilting nest (1) is 5cm, the height of the desilting nest (1) is 3.5cm, and part of sundries such as silt and rocks with large specific gravity subside in the desilting nest. The height of an inlet of the draining nest (2) is 0.5cm, and due to the fact that the inlet is small, large suspended matter cannot enter the drain pipe. The lower end of the draining nest (2) is large, small suspended matter and silt entering the draining nest are flushed away by the water flow, and the self-blocking risks are reduced.

Description

Anti-blocking rainwater lid

Technical field

The anti-blocking rainwater lid of patent of the present invention relates to the urban construction field, relates in particular to municipal sewerage engineering.

Background technology

Rainwater lid drain hole common in the city is a rectangle, and rectangle has 20-30mm wide.The main problem that exists is: leaf, silt, twig, paper scrap, gravelstone is first-class can get into drainage pipe from this drain hole.Though drainage pipe is provided with catch-basin at a certain distance, silt can not be deposited in the catch-basin fully yet, because the proportion of foreign material such as leaf, branch and water is suitable; Effect of settling is not good, may be deposited in a certain position of drainage pipe, along with gathering of drainage pipe foreign material; The silt that comes subsequently will further be piled up, because silt is more tiny, with the person's of plaing a part sealant; The intensity of foreign material and the compactness of silt; Make the local even all obstructions of gutter, make current freely not cause city ponding, cause waterlogging.。

Summary of the invention

The anti-blocking rainwater lid of patent of the present invention mainly is for reducing the obstruction risk of drainage pipe.

The design scheme of the anti-blocking rainwater lid of the present invention is: the rain lid is provided with the desilting nest deposition part proportion material bigger than water; The drain hole design is smaller, can stop than bigger material to get into drainage pipe; Drain hole is inclined upwardly, and can reduce floater and get into drainage pipe.

The beneficial effect of the anti-blocking rainwater lid of the present invention is: because foreign material such as minimizing silt get into drainage pipe, can reduce drainage pipe to stop up risk, reduce city waterlogging risk.

Specific embodiments

The anti-blocking rainwater lid of patent design of the present invention is made up of desilting nest (1) and draining nest (2), and the number of desilting nest (1) and draining nest (2) is by the decision of water cover area size.Rainwater lid edge stays 3cm to be used for fixing above the drainage pipe.The wide 5cm of desilting nest (1), high 3.5cm, the foreign material that part silt and stone geometric ratio are great will be deposited in the desilting nest, sweep away when being swept the floor by the sanitationman.Draining nest (2) entry design is height 0.5 cm; Because going into young, bigger suspension can not get into drainage pipe, it is big that draining nest (2) is designed to the lower end; The less suspension and the silt that get into will be washed away by current; Thereby avoid stopping up the draining nest, less foreign material are smaller to the drainage pipe influence, thereby reduce city waterlogging risk.

The designing and arranging mouth of a river (3) is lower than delivery port (4), just reduces floating thing and gets into drainage pipe.

Claims

1. anti-blocking rainwater lid is made up of main desilting nest and draining nest two functional areas, it is characterized in that: desilting nest width 5cm, and dark height 3.5cm, the draining nest is designed to entrance height 0.5cm.

2. according to the said anti-blocking rainwater lid of claim 1, it is characterized in that: it is little that the draining nest is designed to the upper end, and the lower end is big.

3. according to the said anti-blocking rainwater lid of claim 1, it is characterized in that: drain hole has certain inclination to make outfall be lower than delivery port.
